Pupil day (Persian: روز دانشآموز), also known as "13-Aban-57"[1][2] is a day of commemoration in Iran.;[3][4] On this day, Iranians remember the massacre of a number of Tehran's pupils who were gathered at the campus of University of Tehran in order to protest against the regime of the Shah of Iran on the morning of 13th Aban (month) 1357 (4 November 1978).[5]
At the mentioned date, i.e. on 13 Aban,[6][7][8] at the demonstration which was also run by other groups of people (as well as pupils), the quarrel was commenced with tear gas, then by bullets. Eventually, 56 pupils—and a number of other presented people—were killed by the army of the Shah; likewise hundreds of them were injured.[9]
